Serious social problems related to the elderly have appeared in the Gangwon Province because the population in this area is rapidly aging. Gangwon has the highest suicide rate and the highest percentage of single households. In the process of preparing for the super-aging society, Time Bank (TB) System has been actively used in 34 countries, especially in the United States, the United Kingdom, and Japan. In Korea, the Gumi Senior Club has joined this system since 2004. TB is a multilateral exchanged system based on the philosophy that everyone's time is valued equally. Time credits are given to the person who provides social services, such as citizen participation and elderly care. People receive the desired services using time credits or donating them. If this system were applied to the Gangwon Province in accordance with its characteristics, it would help to reduce the elderly's prejudices and manage their diverse health problems. A virtual local currency using IT technologies is needed to boost the regional economy. The elderly's participation in TB is strongly needed. Future research about the effectiveness of health management is then discussed.

클라우드 컴퓨팅 패러다임의 등장에 따라 다수의 클라우드 서비스와 클라우드 사용자를 연계해 주는 CSB(Cloud Service Brokerage) 라는 개념이 제시되었다. CSB 에 등록되어 비슷한 기능을 제공하는 클라우드 서비스들은 제공자마다 성능, 가격 등에 차이가 있으므로, 클라우드 사용자가 클라우드 서비스를 사용하기 위해 적합한 서비스를 찾기 어렵다. 따라서 다수의 클라우드 서비스 중에서 클라우드 사용자의 요구사항에 가장 적합한 클라우드 서비스를 찾아주는 방법을 CSB 에서 핵심적으로 고려해야 한다. 본 논문은 클라우드 사용자의 요구사항을 수집하고 분석하는 방법과 다양한 클라우드 서비스를 명세하는 SAM을 포함하는 CSB 로써 가상 클라우드 뱅크 아키텍처를 제시한다. 본 논문에서 제시한 가상 클라우드 뱅크 아키텍처는 클라우드 사용자의 요구사항에 적합한 클라우드 서비스 제공을 위한 CSB의 참조아키텍처로 활용할 수 있다.

Convergence between technology and financial services is ubiquitous and widespread. Virtual banks represent an important aspect of financial markets that can generate value added for consumers and enhance the quality of financial services. This study explores the effect of innovation characteristics (relative advantage, compatibility, and perceived risk), consumer characteristics (status quo bias), and social mechanisms (network externality: complementarity, numbers of peers) on consumers' adoption intention and resistance to virtual banks. This study adopted an innovation resistance model with two dependent variables: adoption intention and resistance to virtual banks. An online self-administered survey was conducted and 532 or non-users of virtual banks aged 20 to 69 years old were analyzed. Frequency analysis, descriptive analysis, and hierarchical multiple regression indicated that status quo bias, relative advantage, perceived risk, complementarity, and number of peers insignificantly influence the adoption intention regarding virtual banks. Furthermore, status quo bias, relative advantage, perceived risk, and number of peers insignificantly influence the resistance to virtual banks. Female respondents have a lower adoption intention and higher resistance to virtual banks than male respondents. The findings suggest that the innovation resistance model can be useful in understanding consumers'adoption and resistance behavior as well as reveal that innovation characteristics, consumer characteristics, and social mechanism are important antecedent variables of the innovation adoption decision.

가상화폐의 등장은 최근 발전하고 있는 분산원장기술과 함께 중앙은행에서 발행하는 CBDC(Central Bank Digital Currency)에 대한 관심을 고조시키고 있다. 최근 전자화폐의 등장으로 현금 사용이 지속적으로 감소 추이를 보이고 있으며, 일부 국가들(특히, 인구가 적은 편이며, 현금이용 감소에 따른 부작용이 우려되는 국가와 금융 포용수준이 낮은 일부 국가들의 경우)은 이미 중앙은행이 CBDC에 대한 발행을 결정하거나 시험단계에 있다. CBDC 발행이 도래하고 새로운 금융환경이 조성되는 상황에서 정부 및 공공기관의 이를 바라보는 인식이나 태도에 대한 연구는 많이 부족한 상황이다. 실제 정책 입안자들이나 실행자들이 인식하는 CBDC 제도에 대한 태도와 대안이 그 정책의 영향을 받는 일반 사람들이 생각하는 인식과 어떠한 공통점과 차이점이 있는지에 대해 충분히 연구 혹은 분석된 바가 없다. 따라서 본 연구는 빅데이터 분석 방법을 통하여 중앙은행의 CBDC에 대한 공공의 인식과 민간의 인식에 대해 비교해 보고 향후 CBDC의 도입과 관련한 여러 쟁점들을 미리 점검할 수 있는 기회가 될 것이다.

Although the two types of currencies compete, the possibility of a virtual currency price bubble is diagnosed by assuming an economic model with currencies (won, virtual currency) that are intrinsically worthless. The won is supplied by the central bank to achieve the price stability target, while the supply of virtual currency increases by a fixed number. According to the basic price theory equation, as a simple proposition, cryptocurrency prices form a Martin Gale process [Schilling and Uhlig, 2019, p.20]. Based on the existing theoretical proposition, we applied the variance ratio verification method [Linton and Smetanina, 2016] and a simple technical chart method for empirical analysis. For the purpose of this study, the possibility of a bubble was empirically analyzed by analyzing the price volatility formed in the Korean virtual currency market over the past year, and brief policy implications for this were presented.

The digital age start in earnest with the widespread use of the Internet. As a digital product, virtual idols bring new value to the design and dissemination of commercial brand images. "Luo Tianyi" is the world's first avatar and VOCALOID voice bank of Chinese. It has a large number of fans in China and is widely used in brand promotion. Therefore, "Luo Tianyi" is taken as the research object. Initially, we investigated the virtual idols through books, literature on the internet and other materials. Then we discussed semiotics and theories related to culture code brand design methodology (CCBD). After that, putting the above theories into practice, combined with brand design cases, we analyzed the strategy of virtual idols in brand promotion and dissemination, at last, we have the conclusion as followed. The results show that the virtual idols, visual symbol of "Luo Tianyi" can express the Index and Symbol corresponding to the brand information according to the characteristics of the brand. As an image of cultural code, "Luo Tianyi" can present three visual images at the same time, which are contemporary, traditional and future. In addition, these three visual images are presented in a strong and weak combination, which has a positive impact on the visual communication of the brand.

Welding is one of the most fundamental and necessary work in the industry that demand sophistication of skilled workers. This study is to introduce welding simulator as a training tool, to verify its effectiveness and to measure satisfaction of the trainees. A group of freshman students at a Korea Polytechnics College in their twenties with less experience of welding participated in the study. They were divided into two groups and took a traditional training course (comparison group) and a training course with welding simulator applied reality/haptic technology (experimental group) for same hours respectively. To evaluate training effect, a national certificate test and a survey based on Phillips' ROI (Return on Investment) methodology were conducted by the students and the college respectively. And satisfaction survey among the students based on Kirkpatrick's Four-Level Evaluation Model was also carried out. The results showed that all students in the experimental group passed the national certificate test and the ROI of the experimental group for five years were 110% higher than the comparison group. Furthermore, 25% more students in the experimental group replied "very satisfied" about the overall training course and 75% more students in the same group found that the simulation was very similar to the real welding.

Blockchain is a decentralized network in which data blocks are linked. Through a decentralized peer-to-peer network, users can create shared databases, resulting in a trustworthy and aggregated database known as a blockchain that enhances reliability and security. The distributed nature of the blockchain enables data to be stored on multiple nodes, eliminating the need for a central server or platform. This disintermediation significantly reduces the transaction and administrative costs. The blockchain is particularly valuable in applications where reliability and stability are critical because it establishes an open database that ensures data integrity, making it virtually impossible to tamper with or falsify data. This study explores the diverse applications of the blockchain technology in virtual assets, such as cryptocurrency, decentralized finance, central bank digital currency, nonfungible tokens, and metaverses. In addition, it analyzes the potential prospects and developments driven by these innovative technologies.
